Leading edge technology, not afraid to do things differently if it makes sense, agile and low process overhead for getting things done. Clear focus on a simple business model, with clear responsibilities and freedom on how to deliver.

Cons

You have to be comfortable with rapid change, ambiguity and have enough self confidence to cope with the culture. It's not a place for people who like to know what the rules are and follow them.

The company has a really good philosophy about not imposing burdensome processes and rules. It also treats people as adults and assumes everyone knows the best way to get their job done. They are very good at communicating the current thinking of upper management and the current plan and focus, and how they see the future. Compensation is very good.

Cons

There can be a high turnover. People are let go frequently. Can be a bit intense.
